Abstract: An example arrangement for cooling a gas turbine engine includes an air turbine starter having a turbine section for rotationally driving a compressor through rotation of a shaft. An starter air valve is configured to control a flow of pressurized air that flows downstream towards turbine blades of the air turbine starter. An airflow adjustment device (AAD) is configured to adjust the flow when a manual override feature of the starter air valve is engaged based on a rotational speed of one of the shaft and an additional shaft that is driven by the compressor. A governor is configured to control a degree to which the AAD adjusts the flow. The governor is mechanically linked to the shaft through one or more gears and configured to adjust the AAD such that a rotational speed of said one the shafts does not exceed a predefined threshold during a particular operating mode.

Abstract: A solenoid includes a coil defining an axis, an armature disposed radially inward of the coil, and a plurality of linear guides disposed at least partially between a radially inward facing surface of the coil and a radially outward facing surface of the armature. Each of the linear guides has a frictional surface area, with a dimension of the frictional surface area aligned with the axis being larger than a dimension of the frictional surface area aligned with a circumference of the coil.

Abstract: A bleed valve includes a valve housing defining an inlet and an outlet with a flow path for fluid communication from the inlet to the outlet. A poppet head is connected to the valve housing by a primary spring and a secondary spring. The poppet head is configured for movement relative to the valve housing between: a fully open position in which the poppet head is spaced apart from the inlet to allow flow through the flow path, with the primary spring and secondary spring both expanded; a partially closed position in which the poppet head is spaced apart from the inlet but is closer to the inlet than in the fully open position, with the primary spring compressed; and a fully closed position in which the poppet head seats against the valve housing blocking flow through the flow path, with the primary spring and the secondary spring both compressed.

Abstract: An example arrangement for cooling a gas turbine engine includes an air turbine starter, a starter air valve, and an airflow adjustment device. The air turbine starter includes a turbine section for rotationally driving a compressor of a gas turbine engine through rotation of a shaft that connects the turbine section to the compressor. The starter air valve is configured to control a flow of pressurized air along a flow path from a source to turbine blades of the turbine section. The starter air valve includes a manual override feature that allows manual opening of the starter air valve. The airflow adjustment device is configured to adjust the flow of pressurized air along the flow path when the manual override feature is engaged based on a rotational speed of one of the shaft and an additional shaft that is driven by the compressor.

Abstract: A heated valve is provided and includes a valve body having an inlet, an outlet downstream from the inlet and a valve section fluidly interposed between the inlet and the outlet, a valve element operably disposed within the valve section to assume and move between at least a first position at which fluid communication between the inlet and the outlet is prevented by the valve element and a second position at which the fluid communication is permitted and a heating system. The heating system is in operable communication with at least one of the valve body and the valve element and is configured to melt ice that could prevent movement of the valve element between the first and second positions.
